The matching and calculation methods of the dynamic parameters of the automobile drive train are qua

The power transmitted from the engine output shaft is 1When the clutch is working, its combination and separation will cause power loss2The large and small gears in the transmission will lose power in the process of meshing; In the interval between shifts, there is also a loss of power3

The transmission shaft mechanism is mainly the universal joint at both ends of the transmission shaft, and when it works, due to the existence of the angle difference, as well as the loss of internal parts fit, will lose power 4The hyperid gear meshing of the final reducer and the half-shaft mechanism final reducer, and the loss of the parts in the cross shaft differential, are all 5The steering knuckle of the steering wheel and the placement device of the idler wheel will lose power 6

The rolling resistance generated by the tires and the frictional resistance generated in the corners7Other devices include power distribution for the front and rear wheels of four-wheel drive vehicles.

Engine power is transmitted to the transmission via the clutch, then to the final drive differential reducer and half shaft in the drive axle via the cardan drive, and finally to the drive wheels.

The power transmission device between the engine of a car and the driving wheels is called the drive train of the car. It should ensure that the car has the necessary traction and speed under various driving conditions, as well as the functions of coordinating changes between traction and vehicle speed, so that the car has good power and fuel economy; It should also ensure that the car can be reversed, and that the left and right drive wheels can adapt to the differential requirements, and that the power transmission can be smoothly combined or completely and quickly separated as needed. The drive train includes clutch, transmission, transmission shaft, final reducer, differential and half shaft.

The power transmission device between the engine of a car and the driving wheels is called the drive train of the car.

1. The transmission ratio remains unchanged; 2. The meshing angle becomes larger; 3. The tooth side clearance becomes larger; The diameter of the 4-segment circle increases; The 5th index circle remains unchanged.

Generally, most cars use mechanical drive trainsIt consists of a clutch, a transmission, a rotating shaft with a universal joint and a drive axle with a reducer, a differential, and a half-shaft. Function: Transmit the power of the engine to the drive wheels.

The function of the clutch: to ensure a smooth start of the car and a smooth change speed.

Main advantages: The transmission operating system used in the driving process of the car is composed of a clutch, a transmission, a universal transfer transmission equipment and a related drive axle, that is, a power transmission equipment that connects the engine and the four-wheel drive of the car.

The main application functions of the transmission operating system of the car include the function of promoting the car to start, the speed change function, the function of mainly slowing down the speed and the differential function, etc., so as to give the car in the process of driving with sufficient traction and driving speed change, and then can smoothly ensure that the driving car can run and drive more safely and stably.

The basic function of the drive train is to transmit the power emitted by the engine to the driving wheels of the car, generating driving force so that the car can travel at a certain speed. The drive train is generally composed of a clutch, a transmission, a universal transmission, a final reducer, a differential and a half shaft.

The composition and arrangement of the car's drive train varies with the type of engine, the location of the installation, and the purpose of the car. For example, off-road vehicles mostly use four-wheel drive, so an assembly such as a transfer case is added to its drive train. For front-wheel drive vehicles, there are no transmission shafts and other devices in its drive train.
